  • Non-contact transaction system with token presence detection
    Patent number: 5352877
    Abstract: A transaction system includes a portable electronic token and an external read/write unit which communicate by inductive coupling. The read/write unit transmits short pulses of an r.f. carrier when in its dormant or stand-by mode and, upon detecting the presence of a token, switches its r.f. on continuously to power up the token and conduct a transaction. Thus, the system conserves power but can react rapidly when a transaction is necessary.
